SU1597327A1 - Reservoir for liquid - Google Patents

Abstract

The invention relates to devices that provide for the storage and discharge (discharge) of highly viscous liquids, in particular resins. The aim of the invention is to improve the performance and completeness of discharge of fluid from the tank. Inside the rigid metal housing there is an elastic sheath for the fluid, connected to the feed and drain openings. On the outer surface of the shell are fixed elements made of magnetic material or in the form of suckers. When discharging, compressed gas is supplied to the envelope. The design of the shell walls and the presence of elements fixed on the shell contribute to an increase in the rate of fluid flow and prevents the formation of an air funnel. 5 il.

Description

The invention relates to devices that store and dispense highly viscous liquids, and can be used in the petrochemical and chemical industries.

The aim of the invention is to increase the productivity and completeness of the discharge.

FIG. 1 shows a reservoir filled with a highly viscous liquid, a vertical section; in fig. 2 - magnetic plate; in fig. 3 - suction cup; -Fig. 4 - tank, the position of the elastic shell in the process of draining; in fig. 5 - the same, at the final stage of discharge.

The tank includes a housing 1, a loading port 2 for filling liquid, a drain opening 3 with a locking member 4, an elastic shell 5, the wall thickness of which increases towards the drain opening 4. Elements 6 are evenly fixed on the outer surface of the shell 5, made in the form of plates of magnetic material or suction cups 7. The tank also contains a node 8 for feeding compressed gas under an elastic shell.

The tank works as follows.

When the tank is filled through the loading port 2 with a highly viscous liquid (Fig. 1), the elastic shell 5 abuts the inner surface of the tank housing 1 under the action of fluid pressure and is attached to it with the help of elements 6 in the form of magnetic plates or suction cups 7.

When the fluid is drained, the node 8 is connected to the source of compressed gas, the locking member 4 is opened and pressure is created under the elastic sheath 5. This begins to drain the fluid from the reservoir. As the tank is emptying, the shell 5 is inflated under the action of the compressed gas and moves the liquid from the walls of the tank to the drain hole. The movement of the fluid occurs both as a result of its movement together with the inflating elastic sheath 5, and as a result of the vertical inclination of the walls of the sheath 5, contributing to the intensive draining of the liquid. As the wall thickness of the shell increases towards the drain hole, the movement of the shell 5 is as large as possible.

in places of smaller thickness of its walls corresponding to the peripheral zones of the tank. This leads to the movement of fluid from the peripheral zones of the reservoir to the central zone above the drain hole and prevents the formation of an air funnel on the free surface of the fluid. As the shell 5 is inflated, the elements 6 are separated to interact with their case, made of magnetic material or suction cups 7, from the inner surface of the reservoir. This leads to periodic oscillations of the walls of the diaphragm, thixotropic destruction of the structure of a highly viscous fluid and a decrease in its viscosity, which contributes to the intensive draining of fluid from its walls, which increases the efficiency of discharge.

At the final stage of draining, the elastic shell displaces the highly viscous fluid from the reservoir without the formation of air

funnel due to the adjoining walls of the diaphragm to the free surface of the liquid, which leads to the almost complete emptying of the reservoir.
